README

ci-pug is a library for CodeIgniter to enable Pug Template Engine to render views with .pug or .jade extension.

• all files in the view folder ending with .pug or .jade can be rendered from the controllers but you can still use any other files as views. So you're free to use Pug for all your views or just some of them.
• use the 'cache' => true setting to render your views only once and save rendered files the cache folder, then serve cached file with no performance loss, views will be loaded as fast as the equivalent php views. You can also use 'cache' => '/your/cutom/path
• ci-pug wait for you to load it. Only controllers with use Pug; will load the wrapper, and until you call $this->settings() or $this->view() in the controller, the template engine will not be loaded.

Installation

You need PHP 5.4 or later to run ci-pug. If you use a earlier version of PHP we recommand you to upgrade. If you cannot you can download the library version of ci-pug (available on PHP 5.3).

Open a terminal in the application folder in your CodeIgniter project, then enter:

composer require ci-pug/ci-pug

Be sure $config['composer_autoload'] = true; in your application/config/config.php file

How to use it?

application/controllers/Main.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Main extends CI_Controller {

  use Pug;

  public function index()
  {
    $this->view('myview');
  }
}

application/views/myview.pug

doctype html
html(lang='en')
  head
    title My Pug View
  body
    h1 Hello World!

Pass variables

application/controllers/Main.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Main extends CI_Controller {

  use Pug;

  public function index()
  {
    $this->load->vars([
      'title' => 'My Pug View',
      'authors' => [
        'Luke',
        'Leia',
        'Lando'
      ]
    ]);
    $this->view('myview');
  }
}

or

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Main extends CI_Controller {

  use Pug;

  public function index()
  {
    $this->view('myview', [
      'title' => 'My Pug View',
      'authors' => [
        'Luke',
        'Leia',
        'Lando'
      ]
    ]);
  }
}

All variables from ->view() or ->load->vars() are merged and available in the view.

application/views/myview.pug

doctype html
html(lang='en')
  head
    title=title
  body
    ul
      each author in authors
        li=author

Keep rendered views in cache

We recommend you to do it in production to serve the views faster.

application/controllers/Main.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Main extends CI_Controller {

  use Pug;

  public function index()
  {
    $this->settings([
      'cache' => true
    ]);
    $this->view('myview');
  }
}

Or you can use a custom storage folder:

$this->settings([
  'cache' => '/tmp/my-cache-folder'
]);

If the folder does not exists, the library will try to create it.

Return the view instead of displaying it

$content = $this->view('foo', true);
echo str_replace('<hr>', '----------', $content);
// works also with vars
$content = $this->view('foo', [
  'var1' => 1,
  'var2' => 2
], true);
// and also with view auto-selection
$content = $this->view(true);
// see view auto-selection section below

Controller settings

This feature requires PHP 5.6 and allow you to specify settings for the whole controller.

class Welcome extends CI_Controller {

  use Pug;

  const SETTINGS = [
    'cache' => true
    // here, you can add any option
  ];

  public foo() {
    $this->view('welcome/foo'); // will use the SETTINGS class constant
  }

  public bar() {
    $this
    ->settings([
      'cache' => false// will override the SETTINGS class constant
    ])
    ->view('welcome/bar');
  }
}

Tip: you can create and abstract controller with use Pug; and SETTINGS constant, then extend this abstract class from several controllers.

View auto-selection

If you do not specify the view file, the most logic one with the given class and method will be taken:

class Pug_Controller extends CI_Controller {
  use Pug;
}
class Foo extends Pug_Controller {
  public function index() {
    $this->view(); // load application/views/foo/index.pug
    // or application/views/foo.pug if it does not exists
  }
  public function bar() {
    $this->view(); // load application/views/foo/bar.pug
    // or application/views/foo/bar/index.pug if it does not exists
  }
}
class Yep extends Pug_Controller {
  public function index() {
    $this->view([
      'some' => 'var'
    ]); // load application/views/yep/index.pug
    // or application/views/yep.pug if it does not exists
  }
  public function nop() {
    $content = $this->view(true); // load application/views/yep/nop.pug
    // or application/views/yep/nop/index.pug if it does not exists
  }
  public function dontKnow() {
    $this->view('yep/nop'); // load application/views/yep/nop.pug
    // or application/views/yep/nop/index.pug if it does not exists
  }
}

Custom views folder

If you do no store your .pug files in application/views, use the view_path setting:

$this->settings([
  'view_path' => APPPATH . 'pug-templates'
]);
